Validez predictiva de la escala DIAFORA para el riesgo de amputación; en pacientes con pie diabético ingresados en el Hospital General Guasmo Sur durante julio 2022 a enero 2023.

Abstract

Background: Type 2 Diabetes Mellitus is considered the first cause of death and amputations in Ecuador; one of its most frequent complications is diabetic foot with a prevalence of 8 to 13%. The DIAFORA score is intended to be established as a stratifying system for the risk of developing ulcers due to Diabetes and, in turn, as a predictor of amputations in diabetic patients with current lesions. Objective: To demonstrate the validity of the DIAFORA score as a predictor of amputation risk in patients with diabetic foot admitted to the Hospital General Guasmo Sur from July 2022 to January 2023. Methods: An observational, cross-sectional and descriptive study in patients diagnosed with diabetic foot admitted to the Hospital General Guasmo Sur during the period from July 2022 to January 2023. Results: Of the 179 patients studied, 64.8% were male (n=116). In reference to age, the sample mean was 60.44 years, evidencing a predominance of patients under 65 years of age corresponding to 66.5% (n=119). The DIAFORA scale obtained an AUC of 0.895 at a 95% CI; with a sensitivity of 92.37%, and regarding specificity it was 79.17%. Conclusion: Based on the findings, the DIAFORA score can be considered a valid predictor of the risk of amputation due to diabetic foot. The incidence of amputation due to diabetic foot is high in our environment; male patients in an age range under 65 years of age tend to suffer amputations as a therapeutic outcome of diabetic foot more frequently.
